    Journal: Org Biomol Chem; 2013 Mar 07; 11(9):1502-10. PubMed ID: 23338157.
    Abstract:
    2-Carbomethoxy-3-hydroxyquinoxaline-di-N-oxide was identified as an efficient novel ligand for the copper-catalyzed coupling of aryl halides with various phenols under mild conditions. The catalytic system shows great functional-group tolerance and excellent reactive selectivity.
